                                                                                                         ~

for system, structure:or outside area. q 8.1.2 Evaluate the overall scope of the survey unit by reviewing _the= history file and supporting documentation, and conducting-  ; walkdowns as necessary. This ovaluation determines the.need for- -{ breakdown into subunits. l 8.1.3 . Establish the subunits needed to_ support the survey design: q considering the physical scope and characteristics;offthe_surveyi -j unit. Guidance for' establishing subunits is provided:in Sections! y

8. 2 (systems) , - 8. 3 (s truc turea ) ,2 and' 8.4 ~ (outside are~as)-

v 8.1.4 Each subunit'must be treated as a " population",11 e., the measurements selected for the subunit must show that the-subunit. independently satisfies the applicable release criteria.

                                                                                                                       ~

8.1.5 The' entire. survey unit must-be covered-in the breakdown into T subunits. The minimum number of subunits is zero;.in'the case. where this occurs the_ survey' unit: consists of aLsingle population which encompasses the entire-survey _ unit. 8.1.6 Survey. subunits are disjointf sets _ of obj ec ts,; i .e. , no item is z contained la more than1one: subunit. URIS: The survey design may include multiple subunits which reside in the same physical territory, but each; subunit "contains" unique objects. For exam'ple .

                  .1      The population to be_. sampled is established as a list of all-3                         the items numbered sequentially from 1-to.N. wh'ere N is the-total number of items.
                  .2      The sample size , n, 1.e . , the required ' nunitier of -

measurements:(survey points or measurement locations)-is-determined, usually a minimum-of 30. W

                  .3      The required-number of-items'is selected from=the-population list by using a random number table or.a__ computer random-number generator approvedLby the Termination Survey; Engineers (Ref ll.9).

8.1.13 Identification-coding of the design breakdown structure must I follow the convention in Appendix.12.4 Observe the-overall data i strweture for the survey design in the survey instructions and data sheets using the following hierarchy: Survey unit; Subunit; Survey location; measurement point, Guidance for applying this breakdown in a consistent fashion to systems, structures and outside areas is given in Appendix 12.4. 8.1.14 The basic content and assembly of survey packages is periormed in accordance with SP67X001.02 (Ref.11.4). Survey packages are assembled in a manner which allows them to be divided into sub-packages, to allow performance of survey activities in parallel if necessary. Preparation and use of sub packages is in accordance with the following:

                            .1     The division into sub-packages for structures and outside areas generally is by subunit.
                            .2     For system survey units, breakdown into sub-packages for individual components is acceptable
                            .3     The survey design breakdown of the :urvey unit shall be clearly outlined on the cover page(s) (General Instruction Form, Ref.11.4) at the front of the survey package master.

4 The design breakdown and survey unit description information shall be maintained in the s.urvey unit file. The breakdown listing shall i.dentify the existence of all sub-packages.

                             .5     Each sub package shall be assembled in a separate folder labeled with the identification of the survey unit and subunit (or component) covered by the sub-package.
                             ,6     Each sub-package shall contain the appropriate instructions and data sheets for the survey package covered by the sub-package. Each sub-package data sheet shall be labeled to properly identify the survey unit or sub-unit (or component)               -

to which it belongs. 8.1.15 QC replicate surveys are designed f or each survey unit. A separate survey package shall be prepared for each QC replicate survey in accordance with SP67X001.02 (Ref.ll.4), maintaining conformance with the established criteria of the Termination Survey Quality Control Procedure (Ref.11.11) for replicate QC measurements.

8.2 Survey Design for Systems l This section provides the directions necessary for the design of a system survey and the approval process for this design. It is generally reccgnizedi and has been noted during the Site Characterization Program, that contamination generally is not evenly distributed within a sy.= tem. Therefore, a biased approach is used to select survey locations for systems. This approach to selection of survey locations favorr. those 1ccations with the highest potential for deposition of corrosion products, taking into account the system design and configuration, operating history, and previous radiological survey results. The established criteria of the Termination Survey Plan (Ref.ll.1) for system surveys shall be applied to the survey design. NOTE: The term " component", as used in this section, refers not only to the conventional system operating components such as valves, pumps, or tanks, but to any survey location selected in a system, which may include runs of piping requiring destructive or non-destructive opening, pipe flanges, spool pieces -- adj acent to conventional components, etc. 8.2.1 The preliminary System Component Listing Appendix 12.6, is prepared individually for each system survey unit by the designated survey designer, and revieweo by toe Radiological < Engineer for Systems. It identifies:

                           .1   the system by name and survey unit number, in accordance with SF67X001.08 (Ref.11.2);

2 the system designator, in accordance with the File Code List (Ref.ll.10);

                           .3    the classification of the system as Affected or Unaffected, in accordance with the history file for the survey unit (Ref.11.3);

4 the sequential number of the component / location I,D, This correspor.ds to the survey instruction form number.

                            .5   components selected, identified by name and component identification number where applicable;
                            .6   the Survey Location Selection Criteria code number from Appendix 12.7, Survey Location Selection Criteria.

Designer shou'Id indicate in the survey instructions that the technician performing the scan enter, alongside the .first measurement point in the " Scan" column of the Survey Data Shaet, the highest value recorded. during the scan, and to mark the reading with an arterisk. The technician should also be instructed to explain, in the Comments section of the Survey Data Sheet, that the value entered applies to all surfaces scanned, and not just to the fixed measurement point locations identified in the Location" column of the Survey Data Sheet (Ref.11.4).

                 .2                   systematic survey of every other crid block - for floors and lower walls of survey units classified as Affected, the starting point is selected at random from the first and second nun.bered grid blocks on the floor, continuing the sequence of every other numbered grid block through the entire floor and then carrying the system across to the nunibered wall grid b' locks. For exanple, when the highest numbered floor grid block falls into the sys ter.atic pattern, select the second numbered wall grid block to continue the sequential alternating pattern. A similar approach is applied to suspect ceilings and upper walls in Affected survty units, where the starting point is selected at random from the first and second grid block of the ceiling, continuing the alternate selection through the ceiling and carrying the sequence across to the grid blocks of the upper walls.

Where the design guide indicates:

                         .1    surface scan 100% - the 100% applies to all surfaces of,the specified area, e.g., "Affected Building Exteriors", and not just to the minimum 30 fixed point measurement : 9 cations.       ---

Designer should indicate in the survey instructions that the highest measurement value be recorded as described above in step 8.3.5.1.

                         .2     E-y detector - preference should be given to the largest-area beta-gamma detector appropriate to the surface to be scanned. For example, for smooth evenly-paved areas indicate the use of the floor monitor rather than the 252 cm 2 probe; for wall surfaces, the use of the 252 cm2 detector is preferred to the llP-210 probe.
                          .3    y detector - the Bieron microRem meter is the instrument of preference for surface scans that call for only a gamma detector. The NaI detector may be used in areas where its extreme sensitivity to background fluctuations is an asset rather than an impediment to the survey.
